Performance Routing Pfr / OER Woes........

Hello again Guy's

Im trying to get PFR working and having a few issues in lab enviroment, I am currently just looking to get a basic PFR fast failover to 192.168.3.0/24, upon which i can build further policies/labs. But alas i am having little luck......

PS The master is also a BR:

Firstly the 2 BGP Routes at the MC:

*> 192.168.3.0      172.31.0.1                           200 4445 4445 i

* i                 192.168.200.2            0    100      0 i

With a secondary static for good measure:

#show run | i ip route

ip route 0.0.0.0 0.0.0.0 192.168.2.250

ip route 192.168.3.0 255.255.255.0 192.168.2.253 255 name TestSecondaryRoutePFR

Hello,

You have defined a learn-list called "Learn_List_Remote1_Prefix" in your learning section.

But in your pfr-map you reference the access-list instead of the learn-list. If you plan to use the automatic learning, then you have to use the learn-list name in your pfr map, ie:

pfr-map Remote_1_General 100

match pfr learn list Learn_List_Remote1_Prefix

Cheers.
